Abstract
The present invention includes a method of creating a shaped image in a workpiece using a high energy source, with the method comprising positioning a layer proximate the workpiece such that the layer prevents debris from the workpiece from dispersing, and directing radiation from the high energy source through the layer to the workpiece, the layer substantially transparent to radiation emitted by the high energy source such that the high energy source is capable of forming the shaped image.
